Thought this would be a fun thread!
I'll start.

Hot Crab Dip
1 8oz package cream cheese, softened
1 cup mayo
2 tsp Old Bay seasoning
1/2 tsp ground mustard
1 lb lump crab meat
1/4 cup shredded cheddar cheese

Mix the mayo, cream cheese, old bay and mustard until well blended.
Add in the crab meat and toss gently.
Spread in a shallow baking dish, sprinkle cheese on top, as well as additional old bay if you'd like.
Bake at 350*F for about 30 minutes, until hot and bubbling.

Enjoy! (As I'm doing right now!)
